  • Publication number: 20210102636
    Abstract: A valve device is provided that is a gas-driven type, is capable of mounting various electronic devices, and solves problems involving wiring or battery replacement. The problem is solved by a valve device including a piston member that drives a diaphragm, an actuator part that receives supply of high-pressure air and drives the piston member, a coil spring that presses the piston member in a direction reverse to a driving direction of the actuator part, and a power generation unit provided in a power generation unit-housing part serving as a supply path of high-pressure air to the actuator part and including a screw rotated by air flow and a commutator generator coupled with the screw. The power generation unit generates power using the high-pressure air supplied to the actuator part and a portion of energy stored in the coil spring.

  • Publication number: 20210102633
    Abstract: A fluid control device is provided in which a temperature sensor is firmly fixed and the thermal contact of the temperature sensor with the inner circumferential surface of a leak port is reliably maintained. A fluid control device 3 holding a temperature sensor 7 has the temperature sensor 7 inserted into a leak port LP and a sensor holding member 8 provided directly above the leak port LP and holding the temperature sensor 7 in a state in which the temperature sensor 7 is inserted into the inside of the leak port LP. The sensor holding member 8 is formed of a base body part 81 disposed directly above the leak port LP and a through hole 8a provided on the base body part 81, the temperature sensor 7 being inserted into the through hole 8a, the through hole 8a communicating with the leak port LP. The base body part 81 has a length that fits in the width of the fluid control device 3 in the short-side direction. The through hole 8a of the sensor holding member 8 and the leak port LP form a predetermined angle.

  • Publication number: 20200284367
    Abstract: To provide a joint block suitable for a fluid control system which, without reducing the supply flow rate of a fluid, is considerably more compact and integrated. The problem is solved by a joint block including a main flow path that includes upstream side and downstream side openings, sub flow paths that includes first and second openings disposed between the upstream side and downstream side openings in a longitudinal direction, and a connecting flow path that is connected to the main flow path at one end part, and includes an opening that opens at an upper surface and opens between the second opening of the sub flow path and the downstream side opening in the longitudinal direction at the other end part. The main flow path is disposed so as to partially overlap with the sub flow paths and the connecting flow path in a top view.

  • Publication number: 20190390811
    Abstract: A joint includes a first block, a second block, and a single pipe section connecting the first block and the second block. The first block, the second block, and the single pipe have a first gas passage and a second gas passage inside therein. The first gas passage is formed so that a first port which opens at an outer surface of the first block, the single pipe section, and a second port which opens at an outer surface of the second block communicate with each other. The second gas passage is formed so that a third port and a fourth port which open at the outer surface of the second block communicate with each other. The second port is disposed between the third port and the fourth port.

  • Publication number: 20190264326
    Abstract: A fluid control system is provided which, without reducing the supply flow rate of a fluid, is considerably more miniaturized and integrated. This fluid control system includes base blocks and fluid devices respectively installed on upper surfaces of the base blocks. The base blocks each include protruding pipe parts protruding in a longitudinal direction. The protruding pipe parts each communicate with a corresponding second flow path. The protruding pipe part on a downstream side end surface of the base block and the protruding pipe part on an upstream side end surface of the base block are air-tightly or liquid-tightly connected to each other by a welding material.
